| 1 | Pathogenesis of achalasia cardia显示文摘Achalasia cardia is one of the common causes of motor dysphagia.Though the disease was first described more than 300 years ago,exact pathogenesis of this condition still remains enigmatic.Pathophysiologically,achalasia cardia is caused by loss of inhibitory ganglion in the myenteric plexus of the esophagus.In the initial stage,degeneration of inhibitory nerves in the esophagus results in unopposed action of excitatory neurotransmitters such as acetylcholine,resulting in high amplitude non-peristaltic contractions(vigorous achalasia);progressive loss of cholinergic neurons over time results in dilation and low amplitude simultaneous contractions in the esophageal body(classic achalasia).Since the initial description,several studies have attempted to explore initiating agents that may cause the disease,such as viral infection,other environmental factors,autoimmunity,and genetic factors.Though Chagas disease,which mimics achalasia,is caused by an infective agent,available evidence suggests that infection may not be an independent cause of primary achalasia.A genetic basis for achalasia is supported by reports showing occurrence of disease in monozygotic twins,siblings and other first-degree relatives and occurrence in association with other genetic diseases such as Down's syndrome and Parkinson's disease.Polymorphisms in genes encoding for nitric oxide synthase,receptors for vasoactive intestinal peptide,interleukin 23 and the ALADIN gene have been reported.However,studies on larger numbers of patients and controls from different ethnic groups are needed before definite conclusions can be obtained.Currently,the disease is believed to be multi-factorial,with autoimmune mechanisms triggered by infection in a genetically predisposed individual leading to degeneration of inhibitory ganglia in the wall of the esophagus. | Uday C Ghoshal Sunil B Daschakraborty Renu Singh | 2012 | World Journal of Gastroenterology2012，18，24： | 20 |
| 2 | Systemic treatment strategies for triple-negative breast cancer显示文摘Triple-negative breast cancer(TNBC) is defined by the lack of immunohistochemical expression of the estrogen and progesterone receptors and human epidermal growth factor receptor 2(EGFR2). Most TNBC has a basal-like molecular phenotype by gene expression profiling and shares clinical and pathological features with hereditary BRCA1 related breast cancers. This review evaluates the activity of available chemotherapy and targeted agents in TNBC. A systematic review of PubM ed and conference databases was carried out to identify randomised clinical trials reporting outcomes in women with TNBC treated with chemotherapy and targeted agents. Our review identified TNBC studies of chemotherapy and targeted agents with different mechanisms of action, including induction of synthetic lethality and inhibition of angiogenesis, growth and survival pathways. TNBC is sensitive to taxanes and anthracyclins. Platinum agents are effective in TNBC patients with BRCA1 mutation, either alone or in combination with poly adenosine diphosphate polymerase 1 inhibitors. Combinations of ixabepilone and capecitabine have added to progression-free survival(PFS) without survival benefit in metastatic TNBC. Antiangiogenic agents, tyrosine kinase inhibitors and EGFR inhibitorsin combination with chemotherapy produced only modest gains in PFS and had little impact on survival. TNBC subgroups respond differentially to specific targeted agents. In future, the treatment needs to be tailored for a specific patient, depending on the molecular characteristics of their malignancy. TNBC being a chemosensitive entity, combination with targeted agents have not produced substantial improvements in outcomes. Appropriate patient selection with rationale combinations of targeted agents is needed for success. | Budhi Singh Yadav Suresh C Sharma Priyanka Chanana Swaty Jhamb | 2014 | World Journal of Clinical Oncology2014，5，2： | 18 |
| 3 | Homocysteine mediates transcriptional changes of the inflammatory pathway signature genes in human retinal pigment epithelial cells显示文摘AIM:To test whether homocysteine(Hcy) can influence the transcriptional profile, we hypothesized that Hcy can lead to the induction of proinflammatory molecules in the retinal cells of aging people.METHODS:An unbiased in vitro inflammatory pathway focused study was designed employing retinal pigment epithelial(RPE) cell line, ARPE-19. Cells were cultured in the presence or absence of Hcy to capture target genes' expression profile. Three different concentrations of Hcy were added in the culture medium of confluent monolayers. c RNAs were made from the isolated total RNAs and the labeled c RNA probes were hybridized to microarrays specific for human disease pathway inflammatory cytokines, chemokines and their receptor gene micro-array panels as per manufacture's recommendations. Two Hcy up-regulated molecules:IL6 and CEBPB were further validated via Western blot analysis. Hcy's effect on ARPE-19 cellular morphology and genomic DNA integrity were also evaluated.RESULTS:Gene microarray analyses of RPE cells in response to Hcy treatment revealed alterations in the expressions of several inflammatory gene transcripts such as CCL5, CEBPB, IL13RA2, IL15 RA, IL6, IL8 and CXCL3 that were up-regulated. The transcripts for C3, CCL2, IL11 RA and IL18 genes exhibited down-regulation. The IL6 and CEBPB expressions were subsequently validated at the protein levels. Treatment of the retinal cells with increasing Hcy concentration influenced their density in culture however their morphology and DNA integrity remained unaffected. CONCLUSION:These findings suggest that Hcy can potentially mediate the expression of chemokines,cytokines and interleukins receptors in the retinal cells without having any debilitating effects on their morphology and the genomic DNA integrity. | Mahavir Singh Suresh C Tyagi | 2017 | International Journal of Ophthalmology(English edition)2017，10，5： | 10 |
| 4 | Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732). | Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco | 2012 | World Journal of Gastroenterology2012，18，26： | 6 |

| 6 | Traditional uses,phytochemistry and pharmacology of Clerodendron glandulosum Coleb - a review显示文摘Present review for the first time provides a complete botanical description and information on ethnomcdicinal uses of Clerodendron glandulosum.Coleb(CG:Fam.Verbenaceae).Recent studies conducted from our laborator) provide pharmacological evidence for its anti-hypertensive,antidiabetic and anti-obesity potentials.Further,its beneficial potential in preventing in vitro and in vivo non-alcoholic steatohepatitis and atherosclerosis and potent hcpatoprotective and free radical scavenging abilities along with its acute and sub- chronic toxicologiesl evaluations are also reported from our laboratory.In keeping with its traditional uses,CG extract was capable of ameliorating experimentally induced hypertension,diabetes and obesity.Its beneficial potential against NASH induced oxidative stress and atherosclerosis can be attributed to its potent free radical scavenging potential.Non—toxic nature of CG leaf extract further provides added merit to its reported pharmacological properties.The present review summarizes the pioneering scientific evidence for the pharmacological effects of CG against related metabolic disorders like hypertension,diabetes and obesity along with anti oxidant potential and beneficial elicits against non alcoholic steatohepatitis. | Ravirajsinh N Jadeja Menaka C Thounaojam Thouchom Brojendro Singh Ranjitsinh V Devkar AV Ramachandran | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，1： | 3 |
| 7 | A hypothesis for treating inflammation and oxidative stress with hydrogen sulfide during age-related macular degeneration显示文摘Age-related macular degeneration(AMD) is a leading cause of blindness and is becoming a global crisis since affected people will increase to 288 million by 2040.Genetics,age,diabetes,gender,obesity,hypertension,race,hyperopia,iris-color,smoking,sun-light and pyroptosis have varying roles in AMD,but oxidative stress-induced inflammation remains a significant driver of pathobiology.Eye is a unique organ as it contains a remarkable oxygengradient that generates reactive oxygen species(ROS) which upregulates inflammatory pathways.ROS becomes a source of functional and morphological impairments in retinal pigment epithelium(RPE),endothelial cells and retinal ganglion cells.Reports demonstrated that hydrogen sulfide(H_2S) acts as a signaling molecule and that it may treat ailments.Therefore,we propose a novel hypothesis that H_2S may restore homeostasis in the eyes thereby reducing damage caused by oxidative injury and inflammation.Since H_2S has been shown to be a powerful antioxidant because of its free-radicals' inhibition properties in addition to its beneficial effects in age-relatedconditions,therefore,patients may benefit from H_2S salubrious effects not only by minimizing their oxidant and inflammatory injuries to retina but also by lowering retinal glutamate excitotoxicity. | Akash K George Mahavir Singh Rubens Petit Homme Avisek Majumder Harpal S SANDhu Suresh C Tyagi | 2018 | International Journal of Ophthalmology(English edition)2018，11，5： | 3 |
| 8 | In-vitro scolicidal activity of Mallotus philippinensis (Lam.) Muell Arg. fruit glandular hair extract against hydatid cyst Echinococcus granulosus显示文摘Objective: To investigate new scolicidal agent from natural resources to cope with the side effects associated with synthetic drugs in Echinococcosis. Methods: The scolicidal potential of methanolic fruit powder extract (10 and 20 mg/mL) of Mallotus philippinensis ( M. philippinensis ) was investigated. Viability of protoscoleces was confirmed by trypan blue exclusion method, where mortality was observed at concentration of 10 and 20 mg/mL in 60 min treatment against Echinococcus granulosus ( E. granulosus ), under in-vitro conditions with reference to the known standard drug Praziquantel . Results: At concentration 10 and 20 mg/mL, the mortality rate was observed 97% and 99% respectively for 60 min treatment; while up to 93% mortality was observed with 20 mg/mL for only 10 min treatment. The concentration above 20 mg/mL for above 2 h showed 100% mortality, irrespective of further incubation. Conclusions: As compared with the standard anti-parasitic drug Praziquantel our extract has significant scolicidal activity with almost no associated side effects. | Mayank Gangwar Vijay C Verma Tryambak D Singh Sushil K Singh RK Goel Gopal Nath | 2013 | Asian Pacific Journal of Tropical Medicine2013，6，8： | 3 |
| 9 | Defining acute-on-chronic liver failure: East,West or Middle ground?显示文摘Acute-on-chronic liver failure(ACLF),a newly recognized clinical entity seen in hospitalized patients with chronic liver disease including cirrhosis,is associated with high short- and medium term morbidity and mortality.Noneof the definitions of ACLF proposed so far have been universally accepted,the two most commonly used being those proposed by the Asia-Pacific Association for the Study of Liver(APASL) and the European Association for the Study of Liver- Chronic Liver Failure(EASL-CLIF) consortium.On paper both definitions and diagnostic criteria appear to be different from each other,reflecting the differences in cut-off values for individual parameters used in diagnosis,the acute insult or precipitating event and the underlying chronic liver disease.Data directly comparing these two criteria are limited,and available studies reveal different outcomes when the two are applied to the same set of patients.However a review of the literature suggests that both definitions do not seem to identify the same set of patients.The definition given by the APASL consortium is easier to apply in day-to-day practice but the EASLCLIF criteria appear to better predict mortality in ACLF.The World Gastroenterology Organization working party have proposed a working definition of ACLF which will identify patients from whom relevant data can be collected so that the similarities and the differences between the two regions,if any,can be clearly defined. | Harneet Singh C Ganesh Pai | 2015 | World Journal of Hepatology2015，7，25： | 2 |
| 10 | Genes and genetics in eye diseases: a genomic medicine approach for investigating hereditary and inflammatory ocular disorders显示文摘Past 25 y have witnessed an exponential increase in knowledge and understanding of ocular diseases and their respective genetic underpinnings. As a result, scientists have mapped many genes and their variants that can influence vision and health of our eyes. Based on these findings, it is becoming clear that an early diagnosis employing genetic testing can help evaluate patients' conditions for instituting treatment plan(s) and follow-up care to avoid vision complications later. For example, knowing family history becomes crucial for inherited eye diseases as it can benefit members in family who may have similar eye diseases or predispositions. Therefore, gathering information from an elaborate examination along with complete assessment of past medical illness by ophthalmologists followed by consultation with geneticists can help create a roadmap for making diagnosis and treatment precise and beneficial. In this review, we present an update on ocular genomic medicine that we believe has tremendous potential towards unraveling genetic implications in ocular diseases and patients' susceptibilities. We also discuss translational aspects of genetic ophthalmology and genome engineering that may help advance molecular diagnostics and therapeutics. | Mahavir Singh Suresh C Tyagi | 2018 | International Journal of Ophthalmology(English edition)2018，11，1： | 2 |

| 13 | Combination immunotherapy with Survivin and luteinizing hormone-releasing hormone fusion protein in murine breast cancer model显示文摘AIM To investigate the therapeutic potential of two recombinant proteins, Survivin and luteinizing hormone-releasing hormone (LHRH) fusion protein [LHRH(6 leu)-LTB] for immunotherapy of breast cancer.METHODS Murine 4 T-1 breast cancer model was used to evaluate the efficacy of recombinant proteins in vivo. Twenty four Balb/c mice were divided into 4 groups of 6 mice each. Recombinant Survivin and LHRH fusion protein, alone or in combination, were administered along with immunomodulator Mycobacterium indicus pranii (MIP) in Balb/c mice. Unimmunized or control group mice were administered with phosphate buffer saline. Each group was then challenged with syngeneic 4 T-1 cells to induce the growth of breast tumor. Tumor growth was monitored to evaluate the efficacy of immune-response in preventing the growth of cancer cells.RESULTS Preventive immunization with 20 μg recombinant Survivin and MIP was effective in suppressing growth of 4 T-1 mouse model of breast cancer (P = 0.04) but 50 μg dose was ineffective in suppressing tumor growth. However, combination of Survivin and LHRH fusion protein was more effective in suppressing tumor growth (P = 0.02) as well as metastasis in vivo in comparison to LHRH fusion protein as vaccine antigen alone.CONCLUSION Recombinant Survivin and MIP suppress tumor growth significantly. Combining LHRH fusion protein with Survivin and MIP enhances tumor suppressive effects marginally which provides evidence for recombinant Survivin and LHRH fusion protein as candidates for translating the combination cancer immunotherapy approaches. | Himani Garg Rohit Singh Hada Jagdish C Gupta G P Talwar Shweta Dubey | 2018 | World Journal of Clinical Oncology2018，9，8： | 2 |
